Windows is it's firmware

For a PC I'd rather call it the software, or the OS, and call the BIOS it's firmware. Which can usually be updated for free.

A PC with just a BIOS is unusable, though.

A skateboard without wheels is unusable too, and wheels are not firmware either.

A PC with a BIOS can run free operating systems such as Linux. In contrast, I assume this skateboard can only run their own software/firmware.
